Description

A Geography Teaching Aid for Showing Terrain Structure Suitable for Junior Middle Schools

technical field

The utility model belongs to the field of teaching tools, in particular to a geography teaching tool suitable for displaying topographic structures in junior high schools.

Background technique

The teaching content of junior high school geography includes the overall shape, size and movement of the earth, the division of latitude and longitude, the distribution of land and sea, topographic structure, climate signs, etc. At present, there is a lack of relevant teaching aids when teaching the topographic structure, which makes students The lack of deep understanding of this part of the content will affect the further study of geography in high school and college.

Contents of the invention

The purpose of this utility model is in order to solve the above-mentioned problems that exist in junior high school geography teaching, and a kind of geography teaching aid that is applicable to the display topographic structure of junior high school is provided, and its technical scheme is as follows:

A geography teaching aid suitable for showing topographical structures in junior high schools, which includes a water container, the water container is arranged on a bracket, and a water inlet is respectively arranged on opposite sides of the water container, and the two water inlets are respectively passed through a water inlet pipe It is communicated with a main pipe, and a water outlet is also provided on the water container, and the water outlet communicates with the main pipe through the water outlet pipe. The two water inlets are located at the same height and are located at a position higher than the water outlet. One or more propellers are arranged at the position of the water outlet, and one or more propellers are fixedly connected with a shaft, and the shaft is connected with the main pipe to rotate along the circumference of the shaft, and the shaft is also connected with the hand crank or Motor connection; a vertical water pipe is arranged between the two water inlets inside the water container, the position of the upper port of the vertical water pipe is lower than that of the water inlet, and the lower end of the vertical water pipe passes through the connecting pipe and the water outlet connected.

The beneficial effects of the utility model are as follows: water can be added into the water container without passing through the water inlet, and the propeller is rotated so that the water flows out from the water outlet and enters from the water inlet at the same time, forming a water cycle, and the water on the water surface flows from both sides to the middle , Place a soft floating object on the water surface near the two water inlets, such as a hollow latex sheet. When the two floating objects hit each other, they will squeeze each other, resulting in deformations such as bulges and folds, which vividly simulate the process of geological movement. Deepen students' understanding of topographical structures.
